SPECIFICATION forming part of Letters .Patent No. 581,908, dated May 4, 1897'.` Application led August 2l, 1896. Serial No. 603,484. (N0 specimens.)

.To all whom it may concern:

Be it known that we, JOSEPH FRANKLIN GEN'I` and RICHARD THOMAS GENT, citizens of the United States, and residents of Indianapolis,in the county of Marion and State oflndiana, have invented a certain new and useful Improved Process of Degerminating'Cereals,

of which the following is a speciiication. y

Our invention relates to an improved method of separating the germs from the hard,

, With these Aand other ends in vievvV our invention consists, brieiiy, of crushing or grind ing the grain, such, for instance, as corn; secondly, separating the husks and foreign matter therefrom by afsei'ies of winnowings or screenings or otherwise,and, finally, subjecting the material to a heated revolving roll lor cylinder for separating the germs or Aoily portions from the starchy and glutinous portions.

Our improved method further consists in certain novel features and details hereinafter n fully described, and specifically pointed out in the claims.

In the accompanying drawings we have shown one form or construction of machine for carrying vout our improved method, but we would have it clearly'understood that `We vin no Wise limit our invention tothe structure shown, as it will be evident to those skilledin the art that other machines maybe devised which radically differ fiom the one shown and which in practice would be'capable of carrying out our improved method with as much effectiveness and certainty as the one illustrated. Neither do we in this applicat-ion make any claim to the device shown, as such forms the subject-matter of Aa separate application filed4 by us simultaneouslywitli this application.

In the accompanying drawings, Figure 1 is a sectional View of a machine devised to carry out our improved method, the framework be- `ing omitted. Fig. 2 is a view thereof, partly in elevation and partly in section.f .Figa 3 is a sectional view taken on the line 3 3 of Fig. 2.

To the upper side of any -suitable framework are secured bearings 0 inwhich is supseparating-cylinder To one of the glands c is rigidly secured the gear-wheel D, meshing with the smaller gear-D', the latter being secured to one end of the shaft d, upon or to which 'is rigidly secured the feed-roll E, located above the separating-cylinder B.

For the purpose of im parting motion to the feed-rolland separating-cylinder We secure to the gland c the sprocket or pulley wheel E', which, when revolved, will -by'means of the gland c' and gears D -D revolve the feedrollE and separating-cylinder B in opposite directions, as indicated by the respective arrowsthereon, Fig. 2.

Within the separating-cylinder B is located a stationary pipe F, secured at one end within the cylinder to thesupplyor-'inlet steampipe 'being cut off by the vertical partition f", 1o-

cated within the coupling f. To the opposite 4end of the pipe F and within said cylinder B is secured the outlet-pipe Fzby means of the pipes F2 and F being cut olf by means of the vertical partition f2, located within said coupling f5, the said supply-pipe F' beingl provided with a valve f3 at some convenient point in .its length for regulating the'supply' of steam to said cylinder B, and the outlet-pipe F'2 being provided with a cock f4 folr the purpose of allowing the escape of steam therefrom during .the heating of the cylinder B. To the 9 coupling f5, communication between said outlet-pipe F2 is secured a pipe F3, provided with a suitable valve g and `leading into a trap F4, into which, as' will be'hereinafter understood, is discharged the water of condensation from the interior of the cylinder B.

To prevent any lateral movement of the cylinder B upon the'stationary inlet and outlet pipes F F2, we secure to saidpipes collars G G', fittingr snugly against the inner sides of the cylinder-heads C C', said collar G being provided with a hole or passage-Way g', communicating with a similar opening g2, formed in the inlet-pipe F', this arrangement allowing the steam to pass from the supplypipe F' down through the passage-ways g2 and g into'the cylinder B for the purpose of heating the same. The collar G' is also provided with an opening or passage-way g3, formed in the upper side thereof, communieating with a similarl opening g4, formed in said outlet-pipe F2 for the purpose of allowing'the escape of the water of condensation from the interior of thecylinder into said pipe, and, as before described, through said pipe F3 and into said trap F4.

For the purpose of discharging the condensed steam from the interior of the cylinder B into the outlet-pipe F2 We bolt or otherwise rigidly secure to the inner face or side of the cylinder-head C' a number of bucketshaped wingsH of such shape and contour as to receive and carry up the water from the lower portion of the cylinder and discharge it into the outlet-pipe F2 through the passageways g8 and g4 hereinbefore referred to, it being understood. that said wings lil are stationary with said cylinder-head C and revolve therewith.

Above the feed-roll E is located a suitable hopper into which the material is fed, said hopper consisting of the two'confverging sides I I', the lower edge of the former coming into close proximity to the surface of the feedroll E and the lower 4edge of the latter coming into close proximity with the separatingcylinder B, as shown in Fig. l of the drawings. This hopper is constructed of any suitable size, and in order to regulate the iiow of material therefrom to the feeduroll E we provide a suitable gate therein., consisting of the y gate proper, c', hinged or pivotally secured to the side l', the lower edge of said gate being thus adjustable in a direction either toward or away from the surface of the feed-roll E and held in any suitable adjustment by means of the thumb-sc: ew i.

To the lower edge of the rear side I' of the hopper is secured a scraping-plate i, the latter being adjustable upon said side in a direction either toward or awayfrom the cylinder B by means of the thumb-screw t3, this .scraper being utilized for the purpose of preventing the escape of material down past the cylinder B on that respective side thereof.

Two passage-ways K K are provided immediately belenr said separating-cylinder B,

.to any precise degree of heat.

the passage-way K, as will hereinafter be seen, being utilized for the purpose of conveying the granular and starchy portions of the material from the machine and the latter passage-way K being utilized for the Apurpose ofcarrying away the germs or oily portions of the grain. These passage-ways are formed by means of the partitionsk 702 k3 and the front side of the machine, said passage-way K being preferably formed near the forward side or face of the machine and the passage-way K immediately below the center i of the cylinder B.

Below the cylinder B is located a scraping device consisting, preferably, of a scrapingplate n, vertically adjustable toward or away from the surface of said separating-cylinder' and mounted upon a suitable support n', extending across t-he upper portion of its respective passage-way. l

Having now fully-described one form or structure' of machine devised for the purpose of carrying out our improved method, we will proceed to describe the method itself of treating the material.

The grain-such, for instance, as corn-is rst cracked, crushed, or ground by any suitable means and in any desirable manner separated from the husks, hard and foreign maferial-as, for instance, by a series of screenings or Winnowings-these several steps in the treatment of the grain being well known to those skilled in the art and hence need not be described in detail. The material after thus being ground and cleansed is then fed into the hopper of the machine, steam having been first admitted to the cylinder through the pipe F and passage-ways g g2, the cock f being opent Ne do not confine ourselves With different cereals different degrees of heat will be found desirable. After the cylinder` has become suiiciently heated the cock f4 is closed and the feed-roll E and the separating-cylinder B are caused to revolve, as hereinbefore described. The material X in the hopper is fed onto the roll E and therefrom onto the separating-cylinder B, the feed thereof being regulated by the gate t', said hopper and feedroll being set suiiiciently far back past the center of the separating-cylinder to admit of considerable material accumulating on the top of the latter, as shown at Fig. l. The germs of the grain being soft adhere to the heated revolving cyclinder B and are carried down thereon past the spout K or until they meet the scraping-plate n, whereupon they are scraped off and discharged down the spout K' and thence carried away from the machine,

while the hard or starchy and glutinous por- IIC ters Patent, is-
